| X.4333 To BY.{R.W. Bailey - Chief Engineer} from EFC. EFC1/T8.10.24. X.4333. - 20 HP. DYNAMO No.988 EX CH.21. Reference your EY5/H3.10.24, we have investigated the complaint of this machine and attached is a copy of my assistant's report AC.27, from which it will be seen that to rectify the matter it requires two alterations to the control brush system, one of the holder and one of the springs. It is not considered that there is any fault with the commutator which has assisted in producing the complaint. EFC. | ||
